Question

A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters. Which expression gives the volume of the sphere, in cubic centimeters?

Answer 1

the correct answer is 4/3pi times 10 to the third power

Explanation:

Answer 2

Start with the volume equation for a sphere:

V=4/3pi•r^3

The dimensions of the cylinder allow for a sphere with a diameter of 20 centimeters, so the radius of this sphere will be 10 centimeters. Substituting this into the equation:

V=4/3pi•(10)^3

or the uppermost right answer (B).
